a ball has 2kg*m/s of momentum when thrown with a velocity of 8 m/s outwards. find the mass of the ball

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
